- Fix a crash when exporting a file with a branch from the command line
(bug 4255).
- Exit gracefully and give the user some information if LyX catches an
exception from an external program, such as iconv (part of bug 4385).
- Fix LaTeX output of AMS classes when using layouts like Definition but
not using also Theorem (bug 4282).
