Never mind. We all are, and come back to issues as time permits.

Apparently, not during startup time. Startup is a pretty special time 
for the system. See senders of #processCommandLineArguments. The 
#whenUIinSafeState: in the sender might not be enough.

Tried both ways, I believe.

This image starts up without trouble (provided I add a suitable VM, and 
a CuisV6.sources file, in MacOS, Windows 7 and Ubuntu 64. In all cases 
it opens a walkback due to the missing fonts folder, but otherwise they 
can be used normally.

On Ubuntu, the VM I'm using is

cogspur/squeak -version

It is a bit older. Haven't updated it recently. If this makes a big 
difference, then it would be a VM problem.

I see. The price to pay is that debugging is immensely harder.
