a font cache problem I suspect
Yeah, this is again using Linux Libertine G in a long Writer document. I've not been able to reproduce the crash again with a few attempts. Note that I had opened several similar documents, modified them, and closed most of them. So there may be something with incorrectly freed memory.

Have we a reproducible scenario ? i.e. a document I could open and reproduce the problem with.
Caolan: I've just sent to you the document with which I've experienced the crash several times. This document is generated by R/odfWeave based on an ODF containing code. This means I very often reload the document, and scroll quite fast while it's loading images. I cannot be sure that's the problem, but it seems the crash happens when scrolling too fast while the layout is being updated. But then what would be the relationship with the fonts cache, no idea... Another possible explanation is that running R consumes quite a bit of memory, which triggers delays when reloading the document. Maybe there's a race condition between scrolling and updating the view, which is too hard to trigger under normal RAM conditions.
*grumble*, why am I never able to reproduce these things.
(In reply to Caolan McNamara from comment #19) > *grumble*, why am I never able to reproduce these things. Maybe because your machine is fast and the bug only happens when the system is slowed down by memory pressure? I think we discussed this already. Maybe you could try filling your memory to reproduce these conditions...
Nothing under valgrind either. But now that I think about it I was using an self-build upstream mode 4.2 and not the stock Fedora one which uses system graphite which might make a difference. Will try again.
and nothing for me with 4.2 LibreOffice. Maybe I didn't get the right "G" fonts installed. Can I get the output of fc-list -v ? (if you want to try and get a valgrind trace yourself its... export VALGRIND=memcheck oowriter file.odt > ~/valgrind.log 2>&1 and attach the valgrind.log if office crashes or there is anything suspicious in the log.
Actually I've not been able to reproduce the problem now after quite a few attempts. I seems to only happen when I want to concentrate on my work! Unfortunately, running inside Valgrind is so slow that I really can't work with it waiting for the bug to happen again. Any other debugging solution available? Maybe adding a few lines of code would be enough to print interesting information before the crash happens?
*** Bug 1127567 has been marked as a duplicate of this bug. ***
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. 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 EOL if it remains open with a Fedora 'version' of '20'. 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. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 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 this bug is closed as described in the policy above. 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 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 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. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
