This issue was reported on ticket 13419 in our tracker were some data in the users home directory made rdesktop to crash.
The ticket has the home directory that causes this problem.
Could not reproduce the problem using the "broken" homefolder supplied in the support ticket. It is very likely this problem was caused by the hash string length issue that was mentioned and fixed in r1660.
Unable to reproduce with broken home directory on Ubuntu 12.10. Unable to do a code check since r1660 quoted above is presumably the wrong commit number. Since Samuel was unable to reproduce this either, we can probably assume that this has be resolved. Closing.
