Application: okular (0.17.2) KDE Platform Version: 4.11.2 Qt Version: 4.8.4 Operating System: Linux 3.8.0-31-generic x86_64 Distribution: Ubuntu 13.04 -- Information about the crash: - What I was doing when the application crashed: I was viewing a PDF in Okular (externally opened) and compiled a new version of the file when the program crashed. I found an old bug report from 2010 which seemed to be related but it was marked as fixed. Maybe it is a regression? -- Backtrace: Application: Okular (okular), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Can any of you guys that could reproduce this bug please try with Okular >= 0.19.0 ( KDE >= 4.13.0 ). I know i fixed some bugs regarding refreshing of files and i think this one is one of them. Thanks for caring about Okular :)
I haven't seen it for a while in Okular 0.19.0, but it was always intermittent for me anyway.
I know it's intermitent, please keep an eye open and if it happens again with Okular >= 0.19.0 ( KDE >= 4.13.0 ) report back here :-)
Will do. :-) For me, it was very very intermittent though. I think I only came across the bug once or twice in 50 refreshes.
