Blank Message Box while using a 'raiseException'

Question

One of our customers has reported that they see a blank (no text at all) message box with only an 'OK' button.
The issue not reproducible in any of our development environments. I checked that the following line of code is supposed to throw that error message:
this.raiseException("PER:::PER_EMMNG_DEL_NO_CHANGE", "OBJECT_NAME", null, "Error");
I tried to break the code in my dev environment and noticed that if the message name ("PER:::PER_EMMNG_DEL_NO_CHANGE") doesn't exist in the FND Messages, the message box simply shows the message name (no resolution to message description happens). Also, if the message name does exist but the message description is blank in FND Messages, the message ID (PER-15xxxx) is at least displayed.
I could NOT reproduce the case where the message box was completely blank.
Would there by any particular scenario which leads to this kind of a behaviour?
Any pointers would be helpful.
TIA
