Version:           CVS (using KDE KDE 3.1)
Installed from:    Compiled From Sources
Compiler:          gcc 3.2.2  
OS:          Linux

1) Created a KParts KDE Application with local CVS support (/home/cvsroot)
(Initial creation of repository successfull)

2) Modified a line in main.cpp and wanted to update the repository.
(Now the problem).
(a) Using the context menu->CVS->Commit from File Groups group on file main.cpp gives error:
cd 'src' && cvs -f commit -m 'My nice comment' 'main.cpp'
/bin/bash: line 1: cd: src: No such file or directory
*** Exited with status: 1 ***
(b) Using the same context menu fron FileTree gives the error
cd '/home/mario/test/src' && cvs -f commit -m 'My nice comment' 'main.cpp'
cvs commit: cannot open CVS/Entries for reading: No such file or directory
cvs commit: nothing known about 'main.cpp'
cvs [commit aborted]: correct the above errors first!
*** Exited with status: 1 ***

3) Now checked out the repository into another directory (from konsole) with "cvs co test/testpart": ok.

4) Opened the project in the newly checked out directory: ok.

5) Made some trivial modifications to file main.cpp and tried committing: (a) still fails, while (b) succeeds.
