On last "upgrade" of amd64 wheezy I found Firefox in place of iceweasel. OK, except that the single commercial application in my box (Vuescan) now fails to upgrade
francesco@tya64:~/Vuescan$ ./vuescan
gvfs-open:
http://www.hamrick.com/upgrade-l64.html: error launching application: Failed to execute child process "/usr/lib/iceweasel/iceweasel" (No such file or directory)
francesco@tya64:~/Vuescan$
I was unable to remedy with a softlink. What to do? Thanks
