Freron MailMate

Dear Benny,

Thanks for developping and maintaining such a nice email program.

I have a problem when I want to export messages to mbox format, using the Export bundle. The problem does not happen always, but two out of the three times I tried
When I try to 'Select the Export folder' in the Export bundle sometimes (2 out of three occasions, on two different macs), nothing happens.
When I launch MailMate using the terminal, I get the following error message. Do you have any idea what the problem is?

16:20:43@/Applications/MailMate.app/Contents/MacOS ./MailMate

if [ ! -d "${EXPORT_PATH}" ]; then

END
