Comment 14 for bug 1383404

I'm sorry, i don't know why, but got no mails with the bug updates, so i've not seen this last comments till now :(

Anyway, FWIW, today i was debugging a little (with the "old" code 1 month ago, sorry), and i have done a little patch: simply put this on src\waveform\renderers\glwaveformrendererfilteredsignal.cpp (inside the ::draw method, at the beginning)

const int dataTextureSize = waveform->getTextureSize();
if (dataTextureSize <=1) {
return;
}

sometimes (still don't know why) m_data.size is 0, so getData fails. Mostly happens when the song is not previously analyzed, and if you are *not* doing debug through code setp by step until it fails...

Anyway, will update the revision and then try again...
