Long lines of text without spaces break the word wrap
Usually if you type and send (or copy and paste some text) some long message it will show normally while wrapping to the borders of the current chat window size. But if the line of text (usually URL links) has no spaces and is longer than the current chat windows size it won't wrap and go beyond the border. All subsequent normal long messages will not wrap also and will go to the not seen border set by the long "no gap" message or link before. This will continue until "no gap" message or link move away from the current history in the chat window. Spark should break links into multiple lines and wrap them too.
Yeah, i didn't have 814 build on hand to test, so i have just checked with 2.7.7 final. Same issue is in 814. So it must be the recent changes to Roar plugin made by Wolf, which introduced this NPE. Sorry for blaming you Filed as a separate ticket SPARK-1736. Will merge your PR and hopefully 816 build will have it fixed.
The problem that you are experiencing is caused by the ROAR plugin, and is unrelated to the long-lines issue. As a work-around, disable the plugin. I have provided a fix for the plugin here: https://github.com/igniterealtime/Spark/pull/135
Right, I did download the 815 build but then I was not receiving IM's what so ever. Will eagerly wait for official release
There is a little regression uncovered by speedy. The messages don't come through on a fresh profile.
