[BRLTTY] A bug in release 3.10

[Jean-Philippe MENGUAL]

Hi,

I did all the following:

First, Dave, for the moment I only test 3.a0 release. I'll try svn when
the bug on 3.10 is identified and a fix is tried. On the 3.10, I did
autogen, make distclean. Then configkre. Then I installed.

Here's what sans gdb.

Run displays:
[....] # some exit 0, so everything is good, until

brltty: [New Thread 0x40cbb950 (LWP 23470)]

Then, backtrace says:

That's all. These messages make me... perplex :D If I can understand a
bit where's the problem with "run" output, "backtrace" lets me.... lol

Well I stay tester and you developpers. :D Yo'll be more able than I to
understand what happens I think.

Sincerely, JP
