--- Comment #5 from apaul...@gmail.com --- The command line output is just the following: Unable to open QuickAnnotatingTools XML definition QWidget::repaint: Recursive repaint detected KCrash: crashing... crashRecursionCounter = 2 KCrash: Application Name = okular path = /usr/bin pid = 48724 KCrash: Arguments: /usr/bin/okular KCrash: Attempting to start /usr/lib/x86_64-linux-gnu/libexec/drkonqi [1]+ Stopped okular It looks like maybe something is calling repaint() when it shouldn't be? But it doesn't seem to be anything in the trace, so maybe a repaint is getting triggered accidentally somewhere else, and it just isn't causing a crash until later. Here's a dump with a bit more information, but okularGenerator_ghostview.so doesn't seem to have any debug symbols included in the package, and the other missing frame is unclear what's missing: Application: Okular (okular), signal: Segmentation fault [New LWP 49309] [New LWP 49313] [New LWP 49314] [New LWP 49315] [New LWP 49316] [New LWP 49317] [New LWP 49318] [New LWP 49319] [New LWP 49320] [New LWP 49321] [New LWP 49322] [New LWP 49323] [New LWP 49324] [New LWP 49325] [New LWP 49326] [New LWP 49327] [New LWP 49328] [New LWP 49330] [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". 0x00007f0adcc9499f in __GI___poll (fds=0x7fff530bddf8, nfds=1, timeout=1000) at ../sysdeps/unix/sysv/linux/poll.c:29 __preamble__ [Current thread is 1 (Thread 0x7f0ad910a000 (LWP 49308))] Thread 19 (Thread 0x7f0a811c5700 (LWP 49330)): #0 syscall () at ../sysdeps/unix/sysv/linux/x86_64/syscall.S:38 #1 0x00007f0add0266f1 in QtLinuxFutex::_q_futex (val3=0, addr2=0x0, val2=0, val=<optimized out>, op=0, addr=<optimized out>) at thread/qfutex_p.h:133 #2 QtLinuxFutex::futexWait<QBasicAtomicInteger<unsigned int> > (expectedValue=<optimized out>, futex=...) at thread/qfutex_p.h:135 #3 futexSemaphoreTryAcquire_loop<false> (timeout=-1, nn=8589934593, curValue=<optimized out>, u=...) at thread/qsemaphore.cpp:219 #4 futexSemaphoreTryAcquire<false> (timeout=-1, n=<optimized out>, u=...) at thread/qsemaphore.cpp:262 #5 QSemaphore::acquire (this=0x555f00799480, n=<optimized out>) at thread/qsemaphore.cpp:326 #6 0x00007f0acde78e06 in ??
