[Conkeror] Debian package update?/xul problem

[A.W.]

Considering there's been no commits to Conkeror in a month, and it's
working fine for me, I think it might be a good idea to update the
package, if possible.



Not a Conkeror problem, but one I encountered while using/installing it:
I have a xulrunner that's in my home directory registered globally,
but since 1.9 is in Debian now, I'd prefer to use that.
However, I can't seem to get my machine to do that...
I've tried xulrunner-1.9 --register-global and I get something like:
invalid application.ini path

If anyone knows what's going on/how to fix it, let me know.
