1005. By Ken VanDine on 2014-09-10

fixed the height calculation for the ListView, it was causing a crash onModelChanged

[Sebastien Bacher (seb128)]

Thanks, could you explain why do you need to check the download mode there and what's the difference in the height computation/why the old value was leading to a segfault?

[Ken VanDine (ken-vandine)]

We don't want to tell system-image-dbus to download the system update if auto_download isn't enabled.

I'm not certain why using contentItem to get the height was causing the crash, it seemed to only happen when the system update was already downloaded, so got added to the model while the click updates were getting added. Note the system update gets prepended to the model, so maybe it has something to do with the reordering of the rows.

[Sebastien Bacher (seb128)]

thanks for the details, seems reasonable changes
