Reported using DrKonqi
Created attachment 107983 [details] New crash information added by DrKonqi okular (0.26.1) on KDE Platform 4.14.26 using Qt 4.8.7 - What I was doing when the application crashed: Clicked the button to close okular. The apps had some memory swapped out. Crash after a second or so. -- Backtrace (Reduced): #6 __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51 #7 0x00007f77b6a7b3fa in __GI_abort () at abort.c:89 [...] #9 0x00007f77b6abdf96 in malloc_printerr (action=3, str=0x7f77b6ba9938 "free(): invalid size", ptr=<optimized out>, ar_ptr=<optimized out>) at malloc.c:5049 #10 0x00007f77b6abe7de in _int_free (av=0x7f77b6de0b00 <main_arena>, p=0x7fff3facf500, have_lock=0) at malloc.c:3905 #11 0x00007f77b758e894 in QObjectPrivate::deleteChildren() () from /usr/lib/x86_64-linux-gnu/libQtCore.so.4
Anyone can reproduce this in a modern version of okular, i.e. >= 1.0 ?
