This is a forward of a bug posted by Nathan Willis to Launchpad at https://bugs.launchpad.net/ubuntu/+source/pumpa/+bug/1658795:

Using Pumpa on a machine I just upgraded from 16.04 to 16.10. After the upgrade, reading timelines works, but every attempt to post a new note (including File->New Note, C^N, and clicking on the Comment button on any existing post in the timeline) immediately crashes the Pumpa application.

This makes Pumpa essentially a read-only utility which, while interesting, is certainly insufficient.

I have not encountered any other broken functionality after the upgrade. FTR, I am using Pumpa with an identi.ca account.

As noted by Nathan at https://identi.ca/n8/note/Ty7EH1_TQtqJEq7ogk8VkQ he's using the stock version. According to http://packages.ubuntu.com/yakkety/pumpa this is 0.9.2.

An attempt will be made to backport 0.9.3 to ppa:skellat/tests to see if it can be made available.
