TypeError: __call__() got an unexpected keyword argument 'link'

I'm using Trac 0.11.7 in Debian testing and also AccountManagerPlugin r10593 (same happens with the current stable, too).

After a user registers a new account, he/she is brought to a page where he/she can log in. If the user fills out the login form correctly, then he/she is brought to /prefs/admin which kicks up this error:

2011-08-13 16:32:38,752 Trac[main] ERROR: Internal Server Error:

TypeError: __call__() got an unexpected keyword argument 'link'

I'm using Trac 0.11 and at the top of AccountManagerPlugin api.py, it imports tag_ differently depending on whether trac.util.translation exists. Trac 0.11 doesn't have trac.util.translations.domain_functions, so tag_ ends up coming from Genshi.builder.tag . I'm pretty sure that tag doesn't take keyword arguments:

from genshi.builder import tag
tag("foo")

<Fragment>

tag("foo %{bar}s", bar="bar")

Traceback (most recent call last):

File "<stdin>", line 1, in <module>

TypeError: call() got an unexpected keyword argument 'bar'

I don't know how Trac 0.12 works, but this is a compatibility issue. I fixed it (poorly) like this:

Pretty sure that screws up localization, but I hope it makes the problem clearer.

I screwed up the runtime example of Genshi tag. Here it is again in better formatting:

>>> from genshi.builder import tag
>>> tag("foo")
<Fragment>
>>> tag("foo %{bar}s", bar="bar")
Traceback (most recent call last):

Bah... I thought I was using Debian testing--but that's a different server. This server is Debian stable. Debian stable has Trac 0.11.7.

Similar issues have surfaced several times within the last months. So I'm sure that we'll just not use tag_() once again.

[hasienda]

(In [10596]) AccountManagerPlugin: Fix compatibility with Trac 0.11 once again, refs #8684 and #9092.

Replace tag_ call to prevent TypeError in Genshi used by any Trac 0.11
release.

[hasienda]

(In [10597]) AccountManagerPlugin: Change another critical occurrence of tag_(), refs #9090 and #9092.

[hasienda]

(In [10618]) AccountManagerPlugin: Publish maintenance release 0.3.2, closes #9051, #9082, #9088, #9091, #9092, #9093, #9095, #9099, #9107, #9108 and #9109.

This is an update for current stable at 0.3.1 with a number of fixes
for issues reported within the last weeks.

While they will go into acct_mgr-0.4 too, current code isn't ready for release
yet and will introduce a number of backwards-incompatible changes. So don't
hurry for acct_mgr-0.4 right now.

Just noticed what I'd call a bug in signatures.py and removed unreasonable
dependency on identical absolute path for successful check.
Looks like nobody else tried this by now, right? Hey folks!
