Comment 1 Shlomi Fish 2013-05-30 11:00:08 UTC 
What is DSL in this context? How exactly did the crash happen?
Comment 2 Michael 2013-05-31 11:35:09 UTC 
äh, DSL = *D*igital *S*ubscriber *L*ine - this is my uplink to the Net
Comment 3 Michael 2013-05-31 11:36:31 UTC 
i dont know how exactly happen...  sorry....
Comment 4 Shlomi Fish 2013-05-31 12:37:01 UTC 
So you mean that when you close choqok and the DSL connection abruptly closes, then that confuses rekonq which causes it to crash?

Regards,
