Bug in gnucash? Where to get the sources?

[Roel Schroeven]

Hi,

I think I've found a bug in Ubuntu's version of gnucash: the profit in 
the summary bar shows a different amount than the profit and loss 
report, if I configure both to use the same period. The one in the 
report appears correct, the one in the summary bar is clearly wrong.

I'd like to take a look at the source code to see if I can fix it 
myself, but I obviously need the source code to do that. Where can I get 
the source code that's used to build the version that's in Ubuntu now?

Kind regards,
Roel
