Extreme slowdown on Debian stable

[Andrea D'Amore]

Hello,
I installed Gorm and ProjectCenter on a Debian stable in order to try
a little development with GNUstep. I got a working setup with a
peculiar problem: the interaction in file dialogs is _extremely_ slow,
to the point of being unbearable.

For instance clicking any folder in the column views of the
ProjectCenter save file dialog when creating a new project is received
and reacted after tens of seconds (say, 20). Even keystroke, for
typing in a file name, shows the same behavior.

The system load is minimal, even between an event (key or mouse) and
its effects on the UI. I figure there's some (severe) message passing
slowdown somewhere, because the events are eventually parsed but I've
no clue about how to debug this.

Has anyone experienced the same odd behavior?
Should I install from source?
I tried to avoid mixing system packages with non APT managed software
and installing in a machine local prefix would mean recompile every
program using GNustep.

Is there a system you'd recommend over the other ones in order to have
an updated GNUstep environment (say easily following stable releases)?

The version numbers of installed packages are:

    Gorm 1.2.20
    ProjectCenter 0.6.1
    gnustep-make 2.6.6
    gnustep-base 1.24.7
    gnustep-gui 0.24.0
    gnustep-back 0.24.0
