Bug Description

SRU TEST CASE:
1. Launch the current Ubuntu Software Center in Precise.
2. Search for the "Darwinia" package and view the details view for it.
3. Verify that the description text contains the error "Infectionand" near the end.
4. Close Ubuntu Software Center.
5. Update to the version of software-center in precise-proposed.
6. Launch Ubuntu Software Center again and again navigate to "Darwinia".
7. Verify that the text now correctly reads "Infection and".

SRU REGRESSION POTENTIAL:
Very low, but if there is a regression it would likely show as an error in description text layout or content.

This happens with software-center 5.0.1.4 as shipped with Ubuntu 11.10.
I have created a test package to make it easy to reproduce this. In the test package's control file the description is defined as follows:

---
Description: A test package
 The goal is to test that multi-line descriptions are handled correctly,
 especially with regards to sentences that span more than two lines and how
 spaces and line wrapping is handled.
---

'dpkg --info' shows the description exactly as it was in the control file. However in software-center the description is shown as:

---
The goal is to test that multi-line descriptions are handled correctly, especially with regards to sentences that span more than two lines and howspaces and line wrapping is handled.
---

Notice how the last word of line two got concatenated with first one of line three, resulting in 'howspaces', thus causing users to report typos.

I'm attaching testpkg.tar.bz2. It contains:
 * testpkg_1.0-1_all.deb which is the test package I mentionned above.
 * testpkg, a directory containing the source for building the above package. To rebuild the package, simply do:
    cd testpkg
    fakeroot ./build

Hello Francois, or anyone else affected,

Accepted software-center into precise-proposed. The package will build now and be available in a few hours. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!
