[Asterisk-Users] 1.2.9.1 crashed today

[Matt]

It fuzzed on the first chunk, so I wiped the source directory, re
un-tarred asterisk so it was clean, and then manually applied the
changes.. doing removes and adds where necessary.  So, unfortunately
no, I do not have the information, though I suppose I could run it
again.

Keep in mind, also, that I'm running 1.2.9.1, not svn-trunk.
