Some more information about this (should be forwarded upstream
I guess).

In src/lxterminal.c:terminal_newtab(), at the very end of it,
we see a call to term_set_swicth_accel(), which initializes
Alt+<TabNumber> key sequence to activate the newly created
tab.  This routine (terminal_newtab()) gets called for _Every_
new tab, even for the first one.  So we're getting Alt+1
always bound to "Switch to Tab#1" function, even if we only
have single tab and there's nothing to switch from/to.

The right solution is to bind both Alt+1 and Alt+2 when
creating SECOND tab instead, and unbind both when the
second tab gets closed (so we're with only one tab again).
This is actually exactly how gnome-terminal (for example)
works.

But for that, my knowlege of the code is too limited to
produce a fix.  Should be trivial to do for the upstream,
however (hopefully anyway).

Thanks!
