Package: libpango1.0-0
Version: 1.4.0-3
Severity: grave

gvim, mozilla, gnumeric, ... all die with this version of pango. In
gdb, it is always the same (!) last message:
Cannot access memory at address 0x23bdfe1827ba0000

For e.g. gvim, the last lines of strace are:
open("/home/helge/.gvimrc", O_RDONLY)   =3D -1 ENOENT (No such file or
directory)
open("/home/helge/_gvimrc", O_RDONLY)   =3D -1 ENOENT (No such file or
directory)
open("/usr/share/themes/Default/gtk-2.0/gtkrc", O_RDONLY) =3D 4
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
Vim: Erhielt tA=B6dliches Signal SEGV
open("/tmp/v547830/", O_RDONLY|O_NONBLOCK|O_DIRECTORY) =3D 4
open("/home/helge/.viminfo", O_RDONLY)  =3D 4
open("/home/helge/.viminfo.tmp", O_WRONLY|O_CREAT|O_TRUNC, 0666) =3D 5
Vim: Beendet.
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++

Downgrading to libpango1.0-0_1.2.5-5_alpha.deb cures this problem,
though gvim and gnumeric don't have menu labels, but work fine
(mozilla does have menu labels still, and also works fine). I tried to
do backtraces in gdb with the broken version, but I always get this
"Cannot access memory "-line with the same address.=20

If I can assist you in debugging this, please tell me which
information you need.

Btw. to make sure that really pango causes this (besides downgrading)
i downgraded all other libraries which the affect (but not unaffected
programs like gnotepad+) had in common. No other downgrading cured
this segfaults.
