[Bug 1763762] [NEW] kile crashed with SIGSEGV in operator<()

[asala]

Public bug reported:

On close, Ubuntu reported this crash and, as it's a development version,
I report it just in case it's of any  use... I don't recall what I was
doing and for the moment being it seems not repeating. Low priority,
thus, I guess...
