[Texmacs-dev] [Bug] 1.0.5.11 Two crashes on menu clicks with emtpy document, preamble only

[Karl Hegbloom]

When I have the attached .tm in TeXmacs 1.0.5.11 (compiled from source
found in Debian experimental) I get two distinct crashes.

The first is triggered by clicking the 'Document --> Part' menu item.
It crashes every time with:

 TeXmacs] Guile error: ((wrong-type-arg car Wrong type argument in position ~A: 
~S (1 ()) #f))
 /usr/share/texmacs/TeXmacs/progs/kernel/boot/debug.scm:210:19: In procedure 
car in expression (apply throw err):
 /usr/share/texmacs/TeXmacs/progs/kernel/boot/debug.scm:210:19: Wrong type 
argument in position 1: ()
 
 Fatal error: Widget expected in 'eval_as_widget'
 See file   : object.cpp

The second is triggered by clicking the 'Document --> View --> Edit
Source Tree' menu item:

 Fatal error: empty composite box in 'composite_box::position'

In case it matters, also attached is my version of 'std-math.ts'.
