Your screenchot contsins an alert panel *from* firefox, reporting a
problem *in* firefox (saying that it is already running but not responding).
So that does not look like anything to do with GNUMail (or GNUstep
libraries).
From the content of that alert panel I imagine that:
1. your system is configured to run a firefox command to open a URL.
2. the new firefox program is checking to see if a copy of firefox is
already running, finding that it appears to be, but that the running
copy is not responding to the request to open it.
So you would need to look at whether there really is a copy of firefox
already running.
If so, why is it stuck? Perhaps an earlier open request was for some
URL where the web page content breaks firefox?
If not, why does the new copy think it's running?
You could try giving firefox experts the exact command that's being
used, and asking them why it's not working.

Hello,
As I built again Pantomime and GNUMail from svn revision 947, I noted
a regression about openURL.
- If I create a link within a TextEdit document and I click on it, it
will launch Firefox and open the expected URL.
- If I click on a link within a message with GNUMail, it will produce
a new kind of error. See the screenshot below.

not open a new one nor a new tab with the expected URL.
