When pdflatex exits with an error, it may leave an
unfinished, corrupted PDF. Acrobat, which is invoked
automatically by my output-profile, always badly
crashes when trying to repair those corrupted PDFs.
Sadly, I couldn't stop pdflatex from leaving those
damaged files nor stop Acrobat from trying to repair. :(
Perhaps it might be an idea then to add another option
to the output profiles. Similar to "Stop compiling on
LaTEX error", it could be "Prevent viewing on LaTEX error"?
