Is this bug reproducable for you ? I.e. does it happen often? Sometimes? I added a testcase that runs the same code that triggered the bug but could not reproduce the failure.
The bug is that the bit in the commandline '{days: 6}' is invalid json, it should be '{"days": 6}' instead (note the missing "" around days). But how that got generated invalid is a puzzle as the code uses json.dumps() to generate it (in SpawnHelper.py line 83). ** Changed in: software-center (Ubuntu) Status: In Progress => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to software-center in Ubuntu. https://bugs.launchpad.net/bugs/957599 Title: piston_generic_helper.py crashed with ValueError in raw_decode(): Expecting property name: line 1 column 1 (char 1) Status in “software-center” package in Ubuntu: Incomplete Bug description: Nothing to declare...
