See what are the initial rights for the files that a given GRASS vector layer is composed of:

$ ls -lr dbf/pokrycie_przyborow_u65_10k.dbf vector/pokrycie_przyborow_u65_10k
-rw-rw---- 1 ms      users-grass  466 2008-07-02 19:07 dbf/pokrycie_przyborow_u65_10k.dbf

vector/pokrycie_przyborow_u65_10k:

As can be seen both group and owner can edit data. Now I open the vector in QGIS GRASS Edit, modify a feture and quit. QGIS modifies file access rights for the group, preventing other group members from being able to edit the data from now on:

$ ls -lr vector/pokrycie_przyborow_u65_10k dbf/pokrycie_przyborow_u65_10k.dbf
-rw-r--r-- 1 ms      users-grass  375 2008-07-02 19:14 dbf/pokrycie_przyborow_u65_10k.dbf

Please don't!
