[Test Case]
Install deb package that has no section in instVersion, see if program crashes.

[Regression Potential]
Adds an additional check to if statement to ensure InstVer->Section != 0.

Small patch to fix the crash.

I can confirm that the 0.8.16~exp12ubuntu10.24 packages from precise-proposed fix the problem. I have a customer case where apt-get was segfaulting, and by extension, landscape-client (which uses the apt library) was too.

After installing the update, the segfaults stopped and the wedged activities in landscape completed successfully.

[Bryan Quigley (bryanquigley)]

Customer Confirmed fixed in both 12.04 and 14.04.

[Michael Vogt (mvo)]

Thanks a lot Andreas for the verification!
