[Lazarus] Displaying Xterm does not allow to debug

[ik]

Hello,

If I set in "Run Parameters" to display XTerm, Lazarus does not allow
me to debug the code.
For example setting a break point does not have an effect (but if you
do not display the terminal, then it does stop at the break point).

Is this a bug, or a feature ?

I'm using: Lazarus 1.1 r39183M FPC 2.6.0 x86_64-linux-gtk 2

Thanks,
Ido
