ive had the same problem before, i was sat at the traffic lights and then i couldnt get my gear into first. I thoght o dear gear box nakered.
So i called out the AA but while waiting i noticed that clutch pedal was a not fully retracted, so i put my foot under it and it sprang back
So everything was ok, never done it since, i wouldnt worry unless its doing it alot or often. Sometimes like all things, things dont work
properly. might be a one off like me
