101th history line (Buffer?) always get deleted

[mirror230469]

Hi, after upgrading the profanity from v0.14.0 to v0.15.0, I cannot scroll up above the 100th history line by pressing PAGEUP. The 101th history line keep getting deleted by profanity when new message comes in. This is the error message in profantiy.log everytime it delete the 101th history line.

prof: WRN: Ncurses Overflow! From: muc@somexmppaddress/someusername, pos: 99, ID: some-uuid, message: > The actual message from someusername

The someusername and the actual message is from the new incoming message, not the deleted message. but it always shows pos: 99
