I had eroaster functioning well until now, and I know not what has happened.

I start eroaster as su in a console. When I attempt to burn a compilation, the console gives the following error message:

Traceback (most recent call last):
File "/usr/lib/eroaster/main.py", line 1244, in TimeOutHandler
if (atof(strip(line[9:13])) <= round(float(self.selecteddatasize) /1024)):
File "/usr/lib/python2.2/string.py", line 202, in atof return _float(s)
ValueError: empty string for float()


If I close eroaster and restart, create a compilating and then click "Create Image" button I get the following:

Traceback (most recent call last):
File "/usr/lib/python2.2/site-packages/gtk.py", line 130, in __call__ret = apply(self.func, a)

/bin/sh: -c: line 1: '<bound method mkisofs.command_line of <cdrtools.mkisofs instance at 0x834deac
>> 2>&1 | /usr/lib/eroaster/ecat.py'

... and it hangs.

Can someone help me with this problem?
