Did you sync and unmount the drive before removing ?

TBH I suspect that the problem is not the file system or the operating system.
What do you expect from journaling ?

Unfortunately, this seems to be an error in upstream Debian - the keyboard selection database is corrupt. It will presumably be fixed at some point, but it's not something we've done to it!
If I remember correctly the problem disappeared after the first apt-get upgrade.
