*ERROR*: Assertion failed: (eq (match-end 0) (length string))

I've found that ...
With this abbrev - abbrevs['ec'] = 'emacsclient -c -n'

I enter ec filespec at the prompt and expect an emacs frame to pop up. But if the filespec begins with a hidden directory folowed by the filename (ec .Xincludes/xterm for example) this error message is printed -

ERROR: Assertion failed: (eq (match-end 0) (length string))

This appears to only occur if the directory portion of the filespec begins with a dot and the filename immediately follows the directory name. If the directory name is followed by another directory then all is ok.

In other words this results in the error -

ec .thunderbird/profile.ini

while this works as expected

ec .config/autostart/alacritty.desktop

since the in the latter example the .config directory is followed by the autostart directory then the filename.

Forgot to mention - if I do not use the abbrev there is no error - this works without an error message

emacsclient -c -n .Xincludes/xterm
