Description Johannes Ranke 2008-01-24 17:47:05 UTC

Version:            (using Devel)
Installed from:    Compiled sources
Compiler:          gcc version 4.2.3 20080114 (prerelease) (Debian 4.2.2-7) 
OS:                Linux

Opening the attached PDF makes the system unusable - I can recover it by <CTRL><ALT><BACKSPACE>. I installed poppler 0.6.3, deleted CMakeCache.txt and recompiled okular, but it still happens. I am also attaching the start of a gdb backtrace, but okular doesn't really crash, it just uses a lot of resources, so I don't know how to explicitly kill it without restarting X.

Created attachment 23246 [details]
gdb log

I have no idea if this is helpful or not.

Comment 3 Johannes Ranke 2008-01-24 18:02:25 UTC

BTW, the file can be opened with evince from debian etch (poppler 0.4.5) and debian unstable (poppler 0.6.2) with no probs. Using okular compiled against poppler 0.6.2 produces the same problem. For this reason it seems to me it is not poppler creating the problem, although I don't know if it could be the Qt frontend.

Comment 4 Pino Toscano 2008-01-24 18:25:35 UTC

It seems to be a problem of the Qt4 frontend of Poppler.
Poppler-Qt4 0.4 is not affected as it has no code for reading annotations.

Comment 5 Albert Astals Cid 2008-01-24 21:15:47 UTC

will be fixed in next poppler 0.6 release, due for 26th january

Comment 6 Johannes Ranke 2008-01-24 22:34:04 UTC

I just compiled poppler from git, installed it to /usr/local/ and
rebuilt kdegraphics (after removing CMakeCache.txt). Now I get

What did I do wrong?

Sorry for my scarce background knowledge - I am actually trying to help
by testing and reporting bugs...
