deskbar replicant settings overwrite Vision settings

[pulkomandy]

This happened several time to me, sometimes I boot Haiku and I find Vision has reverted to its default settings. Looking at the settings I see this:

~> message /boot/home/config/settings/Vision/VisionSettings
BMessage(0x0) {
        replicant_path[0] = string("/boot/system/apps/NetworkStatus", 32 bytes)
        replicant_path[1] = string("/boot/system/apps/PowerStatus", 30 bytes)
        replicant_path[2] = string("/boot/system/apps/ProcessController", 36 bytes)
}
failed to unflatten message: Data is not a message

Opening the file with DiskProbe, I see that towards the end there are still some settings from Vision, but apparently the start of the file is overwritten with unrelated data from another file. Checkfs does not see anything wrong with the partition.

Sorry I cannot attach the file, it contains my nickserv passwords.

Filing the ticket under BFS, but since there is no on-disk corruption I suspect the issue may be in some higher layer in the VFS maybe? resulting in two file descriptors being mixed up and the data being written to the wrong file?

Seems likely to be related to #12676.
