Attempting to display a MIME-encoded html message in a virtual folder produced produced the following series of errors, when the supposed current directory of the folder buffer is inaccessible:
(gmail): Inline text/html by emacs-w3m display failed: Setting current directory: no such file or directory, y:/
Error in writing c:/DOCUME~1/login/LOCALS~1/Temp/vm29622935483.html: (file-error Setting current directory no such file or directory y:/)
Launching cmd /c...
apply: Setting current directory: no such file or directory, y:/
Even though we get a complaint from emacs-w3m, the error is actually happening well before it, in attempting to do qp-decode. The backtrace is below. Perhaps call-process-region is being used inappropriately? Or, the Windows path name is incorrectly parsed by some part of call-process-region, so that it is assuming it to be a relative path name? This is happening on Emacs24.
Apparently, call-process-region attempts to first cd to the `default-directory'. Why is the default-directory of the virtual folder set to some random directory?
