Description John Pilkington 2011-11-14 21:08:15 UTC 
Application: konqueror (4.6.5 (4.6.5))
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.4
Operating System: Linux 2.6.35.14-103.fc14.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Several tabs open in konqueror, most viewing folders in file-details mode. Some files in one folder renamed or deleted by other programs; display often updates automatically but sometimes not.  Hit 'refresh' and sometimes the active tab display clears but does not refresh.  Once this has happened the other tabs behave in the same way.  Sometimes see the message of the bug title, sometimes konq aborts.  On restarting konq, all seems ok until it happens again.

This is new after package updates installed on 11 November.  The last update before that was probably around 1 November.  Reported on the kde-fedora list, one reply, reporting similar effect but said to be cured by restarting kde.  Mine doesn't clear.

The crash can be reproduced some of the time.

Comment 1 John Pilkington 2011-11-15 10:56:04 UTC 
I think the trigger for this may be attempting to refresh a tab displaying a .jpg image when the file has changed.

Comment 2 Kevin Kofler 2011-11-15 18:24:45 UTC 
Yes, I suspect it might be that issue (a bad upstream patch we backported, David Faure already fixed his mistake upstream, but we backported only the faulty patch, oops…). That bug causes a file descriptor leak, which might be causing the file opening to fail here (due to running out of file descriptors). Though I'm not 100% sure.
Comment 3 Kevin Kofler 2011-11-18 23:48:34 UTC 
Let's assume this is fixed unless we get evidence to the contrary, since kdelibs-4.6.5-7.fc14 is known bad (as explained above), and the reporter cannot reproduce it with kdelibs-4.6.5-8.fc14 (according to his post to the Fedora KDE mailing list).
