[Qlandkartegt-users] crash when not creating a waypoint

[Sebastian R. <seb...@l0...>]

Hi,

in qlgt 1.7.7 (but bug was also apparent for me on 1.7.5, but never got around to report),

in the Waypoints menu, choose new waypoint,

click on the map, and wait for the waypoint editor window.

Now close the window with the X in the top right corner.
This ends for me in a bus error on OpenBSD 5.6-current amd64.

Program received signal SIGBUS, Bus error.
