Comment # 7 on bug 920260 from Werner Flamme

And from me: I found out that the missing lib for the TB package from
motilla.org is in package dbus-1-glib-32bit. After installing this and
gtk2-theming-engine-adwaita-32bit too, I get 

---snip---
 ./thunderbird

(process:18749): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size
== 0' failed
GLib-GIO-Message: Using the 'memory' GSettings backend.  Your settings will not
be saved or shared with other applications.
---pins---

plus the popup that TB has crashed and the report is sent.

This also happens after "mv ~/.thunderbird ~/.thunderbird.saved", and the
timestamps in there did not change either.
