i recently updated Lubuntu to 13.10 and now after some days Thunderbird stopped working. It just won't open. When i try to open it with the terminal i get the following text:

user@user-rechner:~$ thunderbird

(process:6231): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed

(thunderbird:6231): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::sm-connect after class was initialised

Now i reinstalled it once, deleted this .thunderbird folder in my home directory and it still won't work.

I hope someone can help me. Thanks.
