Bug#435052: iceape-browser: fails to launch from icedove if not already running

[Tom]

Package: iceape-browser
Version: 1.0.10~pre070720-0etch1
Severity: important

when launching iceape from icedove setting network.protocol-handler.app.http
to /usr/bin/iceape, iceape does not start. If iceape was already running,
the selected url is loaded as expected.

The reason seems to be that iceape inherits the environment from icedove, and
icedove sets MOZILLA_FIVE_HOME (in /usr/lib/icedove/run-mozilla.sh, called
from /usr/bin/icedove). Iceape does not set MOZILLA_FIVE_HOME to a proper
value and fails to start. If I unset MOZILLA_FIVE_HOME in /usr/bin/iceape,
then iceape starts up like expected. It seems that this is debian-specific,
as the original seamonkey launch-script does set MOZILLA_FIVE_HOME. In fact,
run-mozilla.sh is equal in seamonkey, firefox and thunderbird, and the original
way of setting MOZILLA_FIVE_HOME seem to be correct.
Is there a reason for handling this differently in iceape, icedove and iceweasel?
