vncviewer: TXScrollbar.cxx:47: void TXScrollbar::set(int, int, int, bool):
Assertion `limit_ > 0 && len_ >= 0 && len_ <= limit_' failed.
Aborted (core dumped)


Version-Release number of selected component (if applicable):
vnc-4.1.2-23.fc9

How reproducible:
100%

Steps to Reproduce:
1. Start vncviewer on a wide screen system
2. Maximise the vncviewer window

  
Actual results:
vncviewer: TXScrollbar.cxx:47: void TXScrollbar::set(int, int, int, bool):
Assertion `limit_ > 0 && len_ >= 0 && len_ <= limit_' failed.
Aborted (core dumped)


Expected results:
Window maximises.
