(In reply to Maarten Lankhorst from comment #3) > Wow, talk about something that should never happen.. Is this still > reproducable on nightly? I think all the fixes for this have been merged now. Maarten, is this correct, can we close this?
If you haven't seen it happen again feel free to close it.
Closing resolved+fixed after 11 months without comments.
