OTR plugin does not always encrypt
I am using the OTR plugin available from the build in plugin manager. It seems to work fine but sometimes the people with I am writing gets the error message that my message is not encrypted. After some more messages and some "refresh OTR" clicks and/or restarting Gajim (or in the worst case removing and re-adding the contact) it works. Sometimes. Sometimes not. My chat partners are using Pidgin, Adium and so on.
Unfortunately there are no steps to reprodouce because it occurs randomly.
