Modified map that doesn't crash

When using some custom map, SC2 may crash. With the latest version of the
Multitasking Trainer by stet_tcl, it does crash as soon as you select the race.
By trial and error, I found out it was the "Enable coach mode:" button that
made it crash. What makes it different fromt other labels is that it has a
style applied to it. That style is ABChoiceBackButtonText. Some other style,
such as ABChoiceButtonText seem to work fine. If I remove that style
specification from all strings in GameString.txt (using Ladik's MPQ Editor)
using some sed command, the map will run fine.

I've attached a version of the map that induces the crash (with a single
ABChoiceBackButtonText label) and a version that doesn't crash. Those should
only work as expected with enUS N.A. retail copies, as the enGB locale has it's
own version of the GameStrings.txt file that I don't think I have modified.

Note that I can't see the ABChoiceBackButtonText style in the list of styles
available from the Starcraft 2 Editor, don't know if it's related.

I've included wine's output for both a run of the crash inducing map and the
one that runs fine. I haven't been able to run it with WINEDEBUG="+all", Sc2
seems to terminate prematurely in that case.

Some other maps also crash for me (ie. The Unit Tester), but I don't know if
it's related.
