I'd like to take a look at this issue if no one is on it yet.

Great! While the error is thrown in remoteFileService.ts, the issue is actually much further up the callstack, in the openerService.ts Take a look at how http and https links are being handled in there. We should probably handle mailto links similarly to http and https links

Thank you for the heads up! I'll take a look into the code :)
