Package: lcdproc
Version: 0.5.2
Severity: normal
Tags: patch
The lcdproc curses driver contains a hard coded keyboard check for
control-L to force a screen refresh. The driver attempts to unget the
character if it wasn't a ^L, but the logic is buggy and discards any
character read *except* for control-L. The attached patch corrects this.
Also needs applying to 0.5.3.
