[Monotone-devel] [BUG] while using the sync command after a propagate

[Benoît PIERRE]

mtn serve crashed with the following output:

 mtn: finding items to synchronize:
 mtn: ticks: c="certificates"/256, k="keys"/1, r="revisions"/64
 mtn:

 Generated from data cached in the distribution;
 further changes may have been made.

The attached jpg describe the state of the DB before the sync. What
happened on the client is changes from the branch whose head is
339bfcd5 (which is also the head of another branch whose changes had
just been propagated from) were propagated to branch whose head is
43d2d1c6, and then a sync command was issued to the server, who
crashed.

I tried restarting the server and sync again, with no luck. I then
tried to check the DB which gave another error (and the attached dump,
sorry, first one got overwritten I guess). After this, I tried
regenerate_caches, then serve and sync again, and everything worked
fine... Another db check did not report any problem.

Q: Why is top posting dumb?
