Solved: Failed to start program. Path or permissions wrong?

Got this error in Qt: "Failed to start program. Path or permissions wrong?" after adding a new drive in our linux developer image in VM-Ware and moving our trunk to it. According to a lot of resources on the Internet the cause should be that the user don't have execute permission. But the user did and there were no difference when using root.

Found out that it was possible to check if mount was set to: noexec by using mount command and it was noexec although according to the GUI in mountmanager it was exec.

Found out that this issue could be solved by doing a remount:

sudo mount -o remount,exec /tmp

After the remount the error disappeared.
