Comment 1 Frederik Bijlsma 2009-01-07 23:27:53 UTC 
After some digging and afterwards googling I found the problem:
(gdb) bt
#0  meta_ui_parse_modifier (accel=0x0, mask=0xbffdaee0) at ui/ui.c:841
#1  0x08072cd1 in mouse_button_mods_handler (pref=META_PREF_MOUSE_BUTTON_MODS,

this is also described in https://bugs.launchpad.net/ubuntu/+source/metacity/+bug/258074 and this also fixes my problem with latest in F10.
I have not verified though if this really has been fixed upstream.
Comment 2 Owen Taylor 2009-11-18 00:18:44 UTC 
Was fixed upstream prior to F11.
