0.50 added all this json kind of configuration and this requires new code that right now fails on latest Jenkins with matrix plugin. And it doesn't matter if previously it was working.
I'm not sure but maybe author could implement a workaround so this json would still fail but at least old kind of configuration could work even with buggy matrix plugin.
I think this would be the best solution till matrix plugin is fixed.
Maybe even adding simple check if build != null could be this workaround.
I saw on my Jenkins server, where I downgraded back to 0.48, the following warning, which seems to be the cause:
Unreadable Data
It is acceptable to leave unreadable data in these files, as Jenkins will safely ignore it. To avoid the log messages at Jenkins startup you can permanently delete the unreadable data by resaving these files using the button below.

JENKINS-29539 NullPointerException on Matrix project
Jaroslaw Niec, so what is the extended choice param plugin doing differently in 0.50, that results in this error in conjunction with Matrix plugin?
I'm not doubting that Matrix is at fault in some way, but the extended choice plugin 0.48 works fine
