Bug#346174: gtk2-engines-smooth: the lastest version (2.6.5-3) makes application segfault

[Emil Nowak]

Package: gtk2-engines-smooth
Version: 1:2.6.5-3
Severity: normal

After upgrading to current SID version some gtk2 apps are crashing. I have
noticed this only on sylpheed-claws-gtk2
I downloaded gtk2-engines-smooth_0.6.0.1-4_i386.deb (the last version from
testing) file from ftp.debian.org and after installing it everything works
fine.
There is gdb output attached but probably It's not useful here.
