Thanks for you work in bisecting the issue to my patch, sorry to have
caused you trouble. After Christian Zigotzky
also reported a problem in this file, I have been able to find a
specific bug and just submitted a patch for it.
Please have a look if that fix addresses your problem, as it's
possible that there was more than one bug introduced
by the original patch.
