Hi,
Since my web browser keeps on crashing on the mail archive site,
I don't know whether this has been posted before. I might assume that,
unless it's a personal problem, it has, as it's _very_ annoying. Anyway,
in essence, when in math mode, trying to put a latex exponential
(^<something>) results in segfault. As an example, open a new document
and go into mathmode, type 1^-7, and here, you get a crash before you
can even write the -7.
I have been able to reproduce this problem with 1.1.5fix2
compiled on my box and with the debian package (1.1.5fix2-1 or something
along those lines). A backtrace follows:

I have also compiled 1.1.6pre1, and the problem isn't present
there. The problem isn't present in 1.1.5fix1 neither.
At any rate, compilation goes smoothly most of the time.
[problem?] I was wondering whether the problem might be due to the way
my keyboard works. I have a Spanish keyboard, and the ^ sign is obtained
by a cunning combination of the key with the "^" sign and space after
it. Applications (rxvt, Xemacs...) seem to take this without a glitch,
and so has lyx in the past, but I was wondering whether that might be an
issue? For people with these sort of keyboards, it's just like getting
a ' by pressing the accent key, and space (instead of a vowel, let's
say). One of my colleagues has been using lyx 1.1.5fix2 extensively in
his computer without further problems (he has a British keyboard) :-?
Thank you,
José
