gdebi crashed with TypeError in checkBreaksExistingPackages()

[Alex Valavanis]

Binary package hint: gdebi

Trying to install a home made deb (attached). As I'm new to packaging, there's a good chance that there's an error in the diff. However, gdebi should tell me about the problem gracefully rather than crashing!

When I tried install the "plymouth_0.8.1-1ubuntu1_i386.deb", the gdebi crashed. I got "plymouth_0.8.1-1ubuntu1_i386.deb" from https://launchpad.net/ubuntu/+source/plymouth/0.8.1-1ubuntu1/+build/1583777 .

When installing the eagle-data deb [1], gdebi crashed.

[1] http://ftp.debian.org/debian/pool/non-free/e/eagle/eagle-data_5.9.0-1_all.deb

[Daniel J Blueman (danielblueman)]

testcase:
$ sudo apt-get install eagle
$ wget http://ftp.debian.org/debian/pool/non-free/e/eagle/eagle-data_5.9.0-1_all.deb
$ gdebi eagle-data_5.9.0-1_all.deb
 -> message stating that eagle-data 5.9.0 will break eagle 5.7.0 should be received
 -> without attached fixes, we get crash

SRU justification:
 - motivation: without fix, users installing a package via GDebi which will break dependencies, will not know why the package can't be installed, since GDebi will crash in this case
 - intrusiveness: the fix is minimal (one-line of code) which affects only the code invoked when packages can't be installed due to dependency breakage
 - potential collateral: none, as there are no child or shared packages of this

Thank you for your work there, Michael could you review the change?

[Luca Falavigna (dktrkranz)]

This is fixed in 0.6.1, starting from Maverick.

[Michael Vogt (mvo)]

Thanks for your bugreport and the patch. I uploaded a fix for this into lucid proposed. testing/feedback in bug #591470 is much apreciated.
