$ fossil update tai
fossil: no such version: tai
$ fossil branch list |grep tai
  tai
  tai_dll

The branch has a single leaf. This command worked fine until yesterday. The latest change that may have done something is adding an event with the same tag as the branch name. We also had a double leaves yesterday late, and we changed one of the branches to "fork a new branch since this checkin" using the ui Edit button.

The current leaf says in Tags and Properties:

    * bgcolor=#c0ffc0 inherited from [e6e7a07477]
    * branch=tai inherited from [e6e7a07477]
    * sym-delivered added by [401c9ad515] on 2011-02-09 02:54:05
    * sym-tai inherited from [e6e7a07477]

Any idea? All our workstation fossil clients show the same behaviour (linux and cygwin).

I could reproduce this another time. An Event page with the same tag as the branch name triggers the problem: then 'fossil update XXX' will get the Event instead of the checkin of the leaf with the name XXX.

This still happens with fossil version [1d93222627] 2011-03-01 19:04:32.

"fossil update branchname" will fail if there is an event tagged with 'branchname' after the branch leaf.

Fossil [d8221b9863] 2011-05-12 still has the problem.
