Description Ralf Corsepius 2009-06-26 13:24:24 UTC

Description of problem:

Clicking onto "Help" in Gimp's main menu fails.

Instead a two message boxes pop up, one telling

"Plug-in crashed: "help-browser"
(/usr/lib64/gimp/2.0/plug-ins/help-browser)

The dying plug-in may have messed up GIMP's internal state. You may want to save your images and restart GIMP to be on the safe side.
[OK]"

another one:

"Could not start the GIMP help browser plug-in.
[Cancel]     [Use Web Browser]"


When lauching gimp from a terminal, at the same time an error message shows:
GLib-ERROR **: The thread system is not yet initialized.
aborting...

Comment 3 Nils Philippsen 2009-06-28 09:49:13 UTC

Hi Ralf, please test gimp-2.6.6-5 once it's available, it contains a backported fix needed for the new webkit version which is in F-11.

With 
# rpm -qa 'gimp*'
gimp-help-2.4.2-4.fc11.noarch
gimp-help-browser-2.6.6-5.fc11.x86_64
gimp-2.6.6-5.fc11.x86_64
gimp-libs-2.6.6-5.fc11.x86_64

The Help->Help crash seems to be fixed.

However, now, the help-browser crashes on some of its submenus, 
e.g. when double-clicking
"1. GIMP User Manual Authors and Contributors"
inside of the help-browser.

I've checked it and seen the same behaviour with webkitgtk-1.1.4 installed. Please update the webkitgtk package to version 1.1.8 which is available from updates-testing and fixed this problem for me.

Comment 6 Nils Philippsen 2009-06-29 09:40:54 UTC

Well, it didn't really, it just crashes a few clicks more down the road.

# rpm -qa 'gimp*' 'webkit*'

gimp-2.6.6-5.fc11.x86_64

I am observing this, when clicking on "1. GIMP User Manual Authors and Contributors":
* (help-browser:29062): CRITICAL **: const gchar* webkit_web_history_item_get_title(WebKitWebHistoryItem*): assertion `WEBKIT_IS_WEB_HISTORY_ITEM(webHistoryItem)' failed

Later, when digging deeper though the menus, similar error messages show up, until the help-browser finally dumps core:

...

Smells like an entirely broken plugin system, to me ;)

Yep.

Not really, it's just the help browser plugin that's broken (with the new versions of webkitgtk which we have in F-11 and later). I've found a patch in the upstream git repo which should fix it for good, though. Expect gimp-2.6.6-6 soon in an updates-testing near you ;-).
