Error when adding a hat using gajim
Aidan Epstein
It looks like the prosody issue tracker is currently unable to
send confirmation emails so I'm sending this here:
What steps will reproduce the problem?
1. Enable the hats module on the muc component
2. Add a hat using the ad-hoc command in gajim
3. See error
What is the expected output?
No errors and hat appears
What do you see instead?

Please provide any additional information below:
It looks like this was last changed here: https://hg.prosody.im/trunk/rev/f9171624fd03
. Should line 1.16 read `legacy_hats_el` or something? Right now
it looks like I'm hitting a circumstance where `legacy_hats_el`
does not get set, so the `legacy_hats_el:tag` call errors.
I'm very unfamiliar with the MUC hats code, but attached is a
patch that may properly fix the issue.

Thanks, applied. Looks like an oversight from https://hg.prosody.im/trunk/rev/f9171624fd03
