"failed to execute default web browser" "input/output error."

[Ye Xu]

hello all,

I am encounter this problem since long, searched on google but still found
no proper answer to it. this problem occurs anytime when I click something,
which will open a url, this error window will popped up, and it is really
frustrating to close it everytime. I had also tried to change the preferred
applicatons in the xfce settings manager, if I set the default browser to
opera, epiphany, konqueror rather than firefox, everything fine, but if I
set it back to mozilla firefox or point it direct to /usr/bin/firefox, the
problem still exist.

any help would be usefull, thx a lot!

I am using xubuntu 8.06 on amd64.

regards

Ye
