Fails to copy tags when fetching branches

[Zygmunt Krynicki]

Copy of IRC session with James:

<zyga> james_w, I think I found a bug in dailydeb
<james_w> zyga, I thought you liked working on difficult things ;-)
<zyga> james_w, http://pastebin.ubuntu.com/623552/
<zyga> # bzr-builder format 0.3 deb-version {debupstream}-0lava1
 lp:versiontools tag:release-1.2
 nest-part packaging lp:~zkrynicki/ubuntu/lucid/versiontools/packaging debian
 this is the recipe file
<james_w> zyga, could you run again with "bzr -Derror dailydeb ..."?
<zyga> sure
<james_w> zyga, or fish the traceback out of your ~/.bzr.log?
<zyga> james_w, here you go: http://pastebin.ubuntu.com/623555/
<james_w> zyga, you are running from trunk?
<zyga> no
<james_w> from the daily packages?
<zyga> Zainstalowana: 2.4.0~beta3-0~bazaar1~natty1
 yes
 hmm
<james_w> as good as then :-)
<james_w> zyga, please file the bug
<zyga> ok, thanks
<james_w> it's not copying tags when fetching rbanches

Copy of the .bzr.log (same as the second pastebin above):
