Archimca,
Sorry that you are seeing this issue.
Can you answer some more questions ?
1) Which source control tool are you using ? Is it Clear Case ?
2) Can you switch to a new workspace and check if the issue persists? Please paste the contents of the .log file which is located at <workspace dir>/.metadata/.log for us.
3) Please take a look at these related links :

I suggest you cross post to the related source control forums for better support.
Hope this helps.
