Created attachment 604031 [details] Cropped screenshot showing missing icon Description of problem: The expected red X icon does not display when the Delete button is added/used on the Mail toolbar. Version-Release number of selected component (if applicable): Fedora 17 XFCE Spin - thunderbird-14.0-1.fc17.x86_64 - thunderbird-lightning-1.6-1.fc17.x86_64 Active Extensions: - Enigmail 1.4.3 - Exchange 2007/2010 Calendar and Tasks Provider 1.8.5 - Lightening 1.6 - Provider for Google Calendar 0.15 How reproducible: 100% Steps to Reproduce: 1. Install thunderbird 2. Show the Mail Toolbar (if not shown) 3. Rightclick on toolbar and choose "Customize..." 4. Find and use the Delete icon NOTE: it's also missing in the toolbar customizing dialog popup. Actual results: The option works, the word "Delete" shows up it's just an empty area for the actual icon image itself on the button. Expected results: Little red X icon for Delete shown as expected. Additional info: This works on my laptop (OSX 10.7) using the Mozilla installer, so I suspect it's a Fedora build issue and not an upstream bug.
I can't reproduce on Fedora 17, what kind of icon theme are you using (Settings/Appearance/Icons)? WFM with Fedora icon theme.
Hi Jan, Thanks for checking, I use the default theme - I dug in with Thunderbird in debug mode (NSPR_LOG_MODULES=all:5) and this appears to actually be a problem with thunderbird-lightening RPM. I confirm if I disable Lightning that the icon appears as expected, so I believe we have an overlay issue. - thunderbird-lightning-1.6-1.fc17.x86_64 I'm moving this bug report over to the thunderbird-lightning queue - I've tried to follow along in the NSPR debug log but am not seeing actual errors ("can't load resource" et. al) generated. If you install this RPM, does your icon now disappear?
Created attachment 604564 [details] non-reproduced screenshot Hm, I can't reproduce even with lightning. Also using default icon set and looks like icons are different. Is Fedora 17 XFCE Spin part of official Fedora 17? If not you'll have to file bug there.
Running F17 KDE here (so it's not just XFCE). Saw that the icon was missing. Uninstalled lightning and saw the icon (a trashcan for me). Reinstalled lightning and the icon remained. Dragged the icon back to the customize toolbar window and the icon disappeared. Dragged it back to the toolbar and the icon came back. Yeesh. With the debugging I do see things like: -1217480960[b741d3d0]: (textrunui) fontgroup: ["Sans Serif"] lang: en-us script: 25 len 67 weight: 400 width: 0 style: normal TEXTRUN [[Bug 847806] thunderbird-14.0-1 missing delete icon on mail toolbar] ENDTEXTRUN So something seems up with icon lookup. Not sure why lightning would have an effect.
It *may* be the Exchange provider who is helping make the issue worse; I tried just disabling this one and it seems to cause the icon to come back on the mail toolbar. I have opened a bug in their bugbase as well to help see if they can figure this out. https://www.1st-setup.nl/bugzilla/show_bug.cgi?id=170 Perhaps they can help shed a clue - but I also confirm what Orion saw, if I disable lightning, restart I can reproduce the behaviour where it shows up on the mail toolbar, but still does not show up in the customize toolbar dialog. weird.
I also have this problem. The Lightning plugin seems to be at fault here. I'm on Fedora 15. Problem on all window managers I tried from Fedora base repos. I've tried moving Thunderbird up to 17.07 and Lightning to 1.9.1 and it is still an issue. I've not turned on debugging yet, but would be happy to if needed. Though I will be moving to Fedora 16 or RHEL6 soon.
Still a problem on Fedora 17 w/ Thunderbird 17.0.6 and the 1.9.1 Lightning plugin.
This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '17'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 17's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 17 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 17's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
