Turns out a customization for MacOS X (disabling DISPLAY so w3m won't
block) was leaking into my Linux setup.

This was hard to debug because mm-display-external doesn't show much
information about the process status.  To debug I used the patch below,
but the function should really capture STDOUT and STDERR of the process.
Is that possible?

Thanks
