Bug#412366: texmacs: infloops and sometimes crashes X when accessing menus

Package: texmacs
Version: 1:
Severity: grave
Justification: causes non-serious data loss

A sure way to crash texmacs from experimental: 

Click on the menu, do not lift the mouse button. Move around with the mouse
in the menu structure. After a while, texmacs starts consuming all the cpu
and X does not allow the focus to be shifted to other windows. Killing
texmacs from the console succeeds, but sometimes X does not recover (i.e.
the screen remains blank when switching back to X) and has to be killed as
well, hence the grave severity.
