Well I had to restart Emacs anyway in order to get a working Gnus back,
so I just checked this now. Apparently edebugging `nnselect-push-info'
was enough to raise the error.
A little while ago I changed the `condition-case' inside `nnselect-run'
into a `condition-case-unless-debug', because it was swallowing useful
errors. I guess both Pankaj's `require' error and my edebugging put
Emacs into a "debug" mode, so an error that was being swallowed was now
raised.
Andy I know you're pretty time-limited now, but what do you think about
this? I've always felt that the `condition-case' inside `nnselect-run'
was kind of dangerous, and it looks like it has been swallowing bugs.
It's not a hard bug to fix, but I'd sure like to address the bigger
issue of raising errors from `nnselect-run'. Do you have any feelings
about it?
(Pankaj, in the meantime I'll do away with the `require' statements in
ebdb-vm.el, thanks for that report.)
