LyX 1.4 crashes when you insert something like "1.3a" into a length widget
(e.g. VSpace, Margins).
The reason is that isValidGlueLength("1.3a") returns true, so widgetsToLength
returns this as the length value. LyX crashes because this is an invalid
length.
Any idea what to do? IMO isValidGlueLength should check if a length is really
valid, i.e. has a valid unit. But how?
