trac suddenly failing

[thomas.besand@…]

Been using trac for a while now, without any problems. It's running under a virtual FreeBSD machine, which makes it difficult for me to update to the newest version. (​http://www.vmware.com/appliances/directory/308) Today this error started to appear. I am not aware of any changes to the system. When choosing 'Browse Source' or 'Timeline' trac fails with the following error message:

svn_time_from_cstring() argument 1 must be string, not None

Traceback (most recent call last):

See #3854, which luckily for you has a patch for 0.9.x ;-)

(That issue should have been fixed in 0.9.7 but that version was never released, as 0.10 was already quite stable at that time)
