If it is small enough you could just attach it in your mail. Better would 
be a bug report and attaching it there after also describing the problem 
and steps to reproduce.

Kill process should do the trick as well - but both are not deleting the 
log file according to my tests.

Strange.

A look at that complete log file might reveal addtional issues.

It would be intersting to have a file with such a degenerated zigzagline.
The effect described and fixed should be of intermittent nature, just in 
the display. If it would persists saving and loading their might be another 
bug involved.

Not that I know of.

Does it help? ;)
