Emacs crashes when setting TeX-Master

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.
If the bug (or problem) is triggered by a specific (La)TeX
file, you should try to produce a minimal sample file showing the
problem and include it in your report.
Your bug report will be posted to the AUCTeX mailing list.
I wanted to define a Tex-Master-File with the appropriate AUCTeX Command in 
the LaTeX Menu. It opens a Minibuffer where I should specify the filename. 
As soon as this Minibuffer is opened I can't make any inputs any more, 
whether with keyboard nor mouse. I have the kill Emacs with Alt+Ctrl+Del to 
restart my work. Any suggestions?
