>From the trace, apparently the issue is the interaction between
evolution, enchant and aspell. Enchant is great, but the definition of
word is much wider than aspell definition of word, and in this case it
tries to get suggestions on a string that does not contain any legal
character. While this call may be seen as an enchant error, aspell
should return an empty list, not a crash. But I am not even sure that
aspell is involved in this crash; I see just a crash in the enchant
backend for aspell, not in aspell itself.

Remark also that is not a word, not even for enchant;
and calling a function with arguments of a wrong type is looking for
trouble (for example, calling enchant -a with 11-22, that is a correct
enchant word, gives meaningful, although useless, suggestions; and
calling it on gives 4 correct words: 1, 2, 02, 148). So
probably the issue is in the evolution/enchant interface. So my
first-sight opinion is that this is an evolution bug.
