[gutsy] kmail crashes when checking for local mail

Binary package hint: kdepim

Hi,

with the upgrade to
ii kmail 4:3.5.7enterprise20070828-0ubuntu

kmail ceases to read mail from my local folder /var/mail/stefan.

Using no locking or FCNTL, it simply hangs saying that it is executing the precommand (not sure if that's the word in english, as kmail doesn't seem to respect LANG).
Using procmail-lockfile, mutt dot-lock or mutt dot-lock with access rights leads to the following crash:

P.S.: Might be some delays I can respond to questions, because I can't read mail due to this bug atm. :/
