Bug#732051: evince: Triggers bug message in libpixman-1

[Uwe Kleine-König]

Package: evince
Version: 3.10.0-1
Severity: minor

Hello,

additionally to the messages by evince that I'm already used to[1] there
are new messages saying:

*** BUG ***
In pixman_region32_init_rect: Invalid rectangle passed
Set a breakpoint on '_pixman_log_error' to debug

When doing as requested the following backtrace can be generated:

#0  0x00007ffff1373150 in _pixman_log_error ()
   from /usr/lib/x86_64-linux-gnu/libpixman-1.so.0
No symbol table info available.
#1  0x00007ffff13702c6 in pixman_region32_init_rect ()

#9  0x00007ffff3c7c9ed in clone () from /lib/x86_64-linux-gnu/libc.so.6
No symbol table info available.

I see that this backtrace isn't as usuable as it could be. I have
evince-dbg installed, so I don't know why there is "no symbol table info
available" for e.g. /usr/lib/evince/4/backends/libpdfdocument.so.
For /usr/lib/libevview3.so.3 the problem might be that evince-dbg ships
"/usr/lib/debug/usr/lib/libevview3.so.3.0.0", but not
"/usr/lib/debug/usr/lib/libevview3.so.3".

I don't have a recipe that triggers that "bug" reliably. If you have
problems to reproduce I can provide you a document that seem to trigger
it from time to time (that is usually after <1 min of browsing).

Best regards
Uwe
