Description Christopher Yeleighton 2010-08-10 23:35:22 UTC
Application that crashed: okular
Version of the application: 0.9.5
KDE Version: 4.3.5 (KDE 4.3.5) "release 0"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.12-0.2-desktop x86_64
Distribution: "openSUSE 11.2 (x86_64)"

What I was doing when the application crashed:
I printed a mail message from KMail to Postscript and converted it to g3 using the command
gs -sDEVICE=dfaxhigh -sOutputFile=/tmp/fax.g3.%d ./print.ps
Then I renamed /tmp/fax.g3.1 to  /tmp/fax.g3 and opened it from Dolphin.

GIMP has no problem with this file
Comment 3 Pino Toscano 2010-08-10 23:51:53 UTC
Hm, a double free or similar, it'd seem.

SVN commit 1161849 by pino:

save the original "data" pointer and delete[] the copy
this way, if we move "data" (for ghostscript/PC research faxes -- see FAXMAGIC) we are always sure to free the right memory buffer
