The tutorial at http://download.freedesktop.org/ldtp/doc/ldtp-tutorial.pdf using launchapp("gedit", 1) to launch applications.  However, this doesn't appear to actually work.

With ldtp 1.6, I get the following:

Python 2.5.4 (r254:67916, Feb 17 2009, 20:16:45) 
[GCC 4.3.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from ldtp import *
>>> launchapp("gedit", 1)
Traceback (most recent call last):

+ Trace 216145

With ldtp 1.2 (from debian stable), I get the following:

Python 2.5.2 (r252:60911, Jan  4 2009, 17:40:26) 
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from ldtp import *
>>> launchapp("gedit", 1)
Traceback (most recent call last):

Note that in both cases, dropping the second argument allows launchapp to succeed.  The tutorial should be updated to drop the second arg as well.
