I'm away on business travel this week, so there won't be a lot going on with
Citadel for a few days. Keep that VM running if you are able, and I will
poke in and test things when I can.
We have determined that the main problem, as suspected, is that the server
crashes whenever it makes a call to libcurl. It doesn't have to be while
sending email; it could be RSS fetching, POP3 fetching, anything that invokes
libcurl makes the server crash. This also means it's easier to test; just
configure a room to pick up an RSS feed and watch it go.
We'll get this. It's just going to take some figuring out. Probably a custom
build of libcurl in the AppImage or something like that.
