Bug#697586: libpango1.0-0: Segfaults and takes Evolution with it

[Fabian Greffrath]

Package: libpango1.0-0
Version: 1.30.1-1
Severity: important

Hi,

Evolution crashes rather regularly for me when clicking on the "New" button to
create a new email. Dmesg tells me that it's libpango that crashes:

evolution[26840]: segfault at 380000000001 ip 00007f7c3396e353 sp
00007fffdfcccbb8 error 4 in libpango-1.0.so.0.3000.1[7f7c33958000+4b000]

I have run evolution in gdb and tried to produce a backtrace of that crash by
clicking the "New" button repeatedly. After about five clicks, I succeeded.
This is what gdb tells me:

Program received signal SIGSEGV, Segmentation fault.
