Ok João, o fiz:

Glibc malloc check Applies to RHEL4 and Fedora Core 3+. 

Newer versions of glibc perform additional internal sanity checks to
prevent and detect data corruption as early as possible. By default,
should corruption be detected, a message similar to the following will
be displayed on standard error (or logged via syslog if stderr is not
open): *** glibc detected *** double free or corruption: 0x0937d008 ***
By default, the program that generated this error will also be killed;
however, this (and whether or not an error message is generated) can be
controlled via the MALLOC_CHECK_ environment variable. You can disable
these internal sanity checks one time per process by doing:

MALLOC_CHECK_=0 cmd

If MALLOC_CHECK_ is explicitly set a value other than 0, this causes
glibc to perform more tests that are more extensive than the default,
and may impact performance.

Should you have a program from a third party ISV that triggers these
corruption checks and displays a message, you should file a defect
report with the application's vendor, since this indicates a serious
bug.

Desistalei todo o adesklets (binários e configurações). Comecei do zero
e, como root, pela via das dúvidas:

ledfis:/root/adesklets-0.6.1# MALLOC_CHECK_=0 && ./configure
ledfis:/root/adesklets-0.6.1# MALLOC_CHECK_=0 && make
ledfis:/root/adesklets-0.6.1# MALLOC_CHECK_=0 && make install

Depois de instalado o yab via /utils/adesklets_instaler, o erro persiste
durante o processo de configuração:

marcelo@ledfis:~$ adesklets_installer
marcelo@ledfis:~$ cd .desklets/yab-0.0.2/
marcelo@ledfis:~/.desklets/yab-0.0.2$ python yab.py
Do you want to (r)egister this desklet or to (t)est it? t
Now testing...
============================================================
If you do not see anything (or just an initial flicker
in the top left corner of your screen), try `--help',
and see the FAQ: `info adesklets'.

marcelo@ledfis:~$ MALLOC_CHECK_=0 && adesklets
marcelo@ledfis:~$

Nada aconteceu...

Acho que terei de encaixar este comando MALLOC_CHECK_=0 no meio do
script em python...

Vou desistir e esperar o pacote na proxima testing.

Obrigado a todos.
