Re: [Monotone-devel] disapprove and kill_rev_locally do not interact well

Hi Daniel!

I actually ran into the exactly same bug today! My original problem is
described here: http://pastebin.ca/320483

For me it was propagating changes from a branch B back into another
branch A where the changes from B have already been deleted:

$ mtn propagate net.venge.monotone.guitone.waf
net.venge.monotone.guitone
mtn: übertrage net.venge.monotone.guitone.waf -> net.venge.monotone.guitone

this is almost certainly a bug in monotone.
please send this error message, the output of 'mtn --full-version',
and a description of what you were doing to address@hidden
do not send a core dump, but if you have one,
please preserve it in case we ask you for information from it.

but the exact same problem also occured on 0.32 (btw... do you notice
that for some unknown reason the "this is certainly a bug in monotone"
is not translated? My translation status was/is ok however for 0.32...)

Yes, regenerating the caches solved the problem for me as well.
