Floating point exception

[mdosch]

When running profanity through torsocks it often crashes with floating point exception. As other programs don't have this issue it seems to be related to profanity. I realized the log is alwas showing a message with a , when it happens. Maybe that's related and something is interpreted as float due to the comma.

Expected Behavior

Don't crash when running in torsocks.

Current Behavior

Crashes with floating point exception

Possible Solution

No idea.

Steps to Reproduce (for bugs)

1. Run profanity in torsocks, e.g. torsocks -q profanity -a myacc -l DEBUG
2. Use and wait.

Context

As it always stop with the same log messae with OMEMO stuff received from the same JID, I could ask the person whether they'd be ok to be contacted by profanity devs for debugging.

Seems like purging the JID in question from all files in ~/.local/share/profanity/omemo/me_at_myserver.de fixed it.

[ProfessorTom]

Does this mean that a solution has been found that needs to be implemented or is this bug ready to be closed without a code change? (I don't know what a JID is in this context. Java ID or something like that?)

[sjaeckel]

FMU it's the third option: there seems to be a bug, but nobody investigated it deep enough to pinpoint the reason and the reporter has found a way to work around it.

JID = Jabber ID, the original term for "XMPP address"

Hi, I noticed this issue and wanted to help. Currently I am running Profanity in WSL (Ubuntu) with torsocks on and I find no issue launching? I wanted to fix this bug (for class but also I think Tor and secure messaging is cool), however I'm having issues reproducing the bug. Anyone else make any progress?

[jubalh]

Hi @OdenDillenkoffer and welcome to Profanity!
I heard from others they couldn't reproduce it too. So its a little a flanky bug.

I would suggest to look at one of our other issues, as we have plenty ;), and pick one of those. Cheers!
