Hello Gustavo, hello other developers
I ran freevo 1.3.4 and lcd.py 1.7 + marquee patches without problems.
Started to use 1.4-rc4 but unpredictable it stopped playing music. Most
time i use "play random recursive". It stopped, the crt and lcd got no
updates. Next key skipped to next title after some seconds. Until it
happend again. Coulndt find a hint in the logs.
Got the cvs-snapshot, run it from a terminal, so could see all messages
and got the problem.
Sometimes, i dont know when and why (just unpredictable) the following
happens: [workaround below all this tracebacks]

This stopped freevo.
key_right had no effect.
key_down skips to next title, with following console log:
force killing with signal 9
Oops, command refuses to die, try bad hack....
Try harder to kill the app....
PANIC
Now we are playing again...
The next one really killed freevo:
Crash!

The error is thrown in the telnetlib, called by pylcd, used by lcd
plugin. This error was not triggered in the 1.3.4, however.
The patch below does not solve the cause of the problem, but prevents
the stop effect (but seems to skip to next file. needs further tests).
Maybe someone has a idea whats going on deep inside and can help find a
solution.
