bugwarrior: 89bff55e533569b7390848f35b9dd95b552e50ae task: 2.6.1

I got this error with a couple of sources.

Something very similar happens on my machine as well:

OS: Arch Linux taskwarrior: 2.6.1 bugwarrior: 1.8.0

only one configured service: gitlab (the instance in question is self-hosted)

Sidenote: I also don't get my command prompt back after the above trace, not sure if there is still something happening in the background, or whether the bugwarrior-pull command simply busy-hangs somewhere ...

Update: looks like the exception is coming from python-taskw ...

My OS ships python-taskw:1.3.0, though there appears to be a newer python-taskw:1.3.1 release (which in particular includes https://github.com/ralphbean/taskw/pull/152 that is supposed to add taskwarrior 2.6.0. compatibility).

Given that I am running a taskwarrior 2.6.1 with a python API wrapper library that does not yet include a fix for 2.6.0 compat ... could that be the source of the problem?

Yes, I believe that is the case but have not confirmed it yet.

Arch Linux (AUR) just bumped python-taskw to 1.3.1, after which the above error is gone, so most likely that was the culprit.

hope that helps anyone else running into this :-)
