Package: claws-mail
Version: 3.5.0-2
For about a month or so I've noticed Claws temporarily pause sometimes when
pening mails. This isn't specific to a particular mail or sender; re-opening
the target it is always successful. The pause usually lasts for about 30-60
seconds and does not seem to be network related, rather that Claws is simply
not repainting to the screen.
If I strace Claws when this occurs, I see it select()ing on two adjacently
numbered file descriptors, which according to /proc/${PID}/fd equate to some
pipes.
Acting on a hunch, one time whilst I was waiting for it I noticed a gpg
process in "--batch" mode, which was blocked reading on another pipe FD. The
process ended suspiciously close to when Claws "unpaused", but this is might
be coincidence.
Any ideas? Assuming some GPG problem, I am not running low on entropy (is
this even needed for decrypting/validating?) As I alluded to above, this bug
is rather non-deterministic and have been unable to develop a testcase - any
pointers on how to collect more information would be useful.
Regards,

You're welcome. A bit late but closing it now ;-)

To be honest I don't know if GnuPG API allows that, but even if that's
possible, the idea of having to tweak the GnuPG configuration twice (in its
own files and within Claws Mail) doesn't seem very interesting and rather
looks more error prone.
If you want that you can always make a start-up script for claws-mail which
switches the GnuPG configuration file before launching claws and restores
it after finishing claws-mail. Though I still don't see the usefulness of
that...
HTH,
