Package: crossvc
Version: 1.5.1-1
Severity: grave
Justification: renders package unusable


Hi, 

I'm trying to run crossvc under Sid. When launching the application, it just
outputs a "Floating point exception" :

did@ddp:~$ crossvc 
Floating point exception

When launched with valgrind, there is some interesting information : 

==9345== 
==9345== Process terminating with default action of signal 8 (SIGFPE)
==9345==  Integer divide by zero at address 0x62CA779F

==9345==    by 0x4A98EBB: (below main) (in /lib/i686/cmov/libc-2.5.so)


I don't know if there have been changes in libqt3 or other dependencies of
crossvc that can cause the bug ...

I can provide more information if needed.

Thanks

Didrik

This bug is caused by the failure of the fglrx driver to return display height
and width values (in millimetres).
This causes divide by 0 segfaults in Qt applications.

See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=384325 for more informations.
