-- Information about the crash:
Different things happen depending on the section of Sensor Browser under which the sensor being added is found.

Crashes:
System > Processors, Cores
CPU Load
Hardware Sensors
Partition Usage (some, sometimes)
Disk Throughput > sd*
Memory > swap
Network

Doesn't crash, doesn't add to graph:
logfiles
Partition Usage (some, sometimes)

Doesn't crash, adds to graph:
System > Uptime
Partition Usage > System Load
Disk Throughput > ram
Memory > physical
Process Count

What happens for a given item under Partition Usage varies. One that gets added one time can crash it the next. It seems like it might partially depend on the order in which multiple things are added.

The crash can be reproduced every time.
