Invalid URI: The hostname could not be parsed.

[maphew]

Current behaviour

• Installed GitLab extension
• restarted Git Extensions
• open a repo folder on disk that had been cloned two years ago by other means from an on-premise GitLab server
• Git Extensions Error Report dialog shows up with the content below

Expected behaviour

That I'd be able to use Git Extensions normally.

Steps to reproduce

• open a repo folder on disk that had been cloned a year ago by other means from an on-premise GitLab server
• Git Extensions Error Report dialog shows up with the content below
• Dismissing the error dialog lets me use Git Extensions, within limits I'll describe later.

Further experimentation reveals that Push fails with "fatal: protocol error: bad line length character: git@". So there's something wrong with the origin's remote configuration. The origin url is git@EXAMPLE.ca:env-devops/geo/ENV-GIS-COE.git.

The root problem is not GitLab plugin's fault, but the error handling might be improved so that the plugin reports the problem instead of crashing.

oh ffs. See comment "I simply forgot to load the private key in pageant what ended in fatal: protocol error: bad line length character: git@. What a misleading error message." on https://stackoverflow.com/questions/8170436/git-remote-error-fatal-protocol-error-bad-line-length-character-unab
