I'm using Fedora 14 KDE Version. I recently discovered that, in Thunderbird, if I click a URL link in an email message, no browser launches, but a cascade of requests are sent to the server. These occur transparently at one-second intervals and do not stop unless/until all Thunderbird processes are killed -- in other words it acts a lot like a DoS attack.
The same problem occurs with Evolution (I note that both Thunderbird and Evolution are Gnome apps). It appears that clicking a link in Thunderbird or Evolution attempts to launch the following process:
ps aux | grep thun
/usr/lib/thunderbird-3.1/thunderbird-bin
The requests look like this to the server -- from Apache access log:
"GET / HTTP/1.1" 200 4099 "-" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.24) Gecko/20111108 Fedora/3.1.16-1.fc14 Thunderbird/3.1.16"
The problem does not occur in KMail -- if I click a link in a message in KMail, Firefox launches (per the KDE file association config). My assumption is that the problem arises from a broken file association in Gtk-related settings -- but here I've already gone out my depth.
I'd appreciate any suggestions for tracking down and repairing the problem.
Thanks!
