[Pan-devel] New segfault in group-preferences editor

[walt]

Hi Heinrich.  Just pulled from git [da407793] and I get a segfault
when I try to edit group-preferences.  The warning about the missing
theme engine is not new.  "hcengine" probably refers to the "high-
color" gtk theme I'm using.  I don't know if it's now a problem for
pan, but I've seen the same warning many times before today.

warning: Could not load shared library symbols for linux-vdso.so.1.
Do you need "set solib-search-path" or "set sysroot"?
