.hgignore crashes Mercurial

[Guido Ostkamp]

Hello,

for our huge project I have setup a .hgignore file of ~650 lines because 
of binaries and auto-generated files (those files either have no extension 
or I would select to many files by patterns).

Now Mercurial refuses to work, on a 'hg status' command I receive the 
following errors:

/usr/local/bin/hg status
** unknown exception encountered, details follow
** report bug details to http://www.selenic.com/mercurial/bts
** or mercurial at selenic.com
** Mercurial Distributed SCM (version 55860a45bbf2)

Is this problem known? Is there a solution?
