Thanks for your bugreport. I can not reproduce this, when I run: $ software-center apt://unity-tweak-tool it opens for me correctly.
Could you please run the command above in a terminal and paste the output here right after it crashed? ** Changed in: software-center (Ubuntu) Status: New => 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/1309398 Title: Software center crash when try to open apt url Status in “software-center” package in Ubuntu: Incomplete Bug description: When i tried to open a apt url(apt://unity-tweak-tool) from google- chrome browser, software center started and crash immediately.
