RGP UI segfaults when loading a capture due to labels

[HansKristian-Work]

Capture: https://1drv.ms/u/c/d2b63e38109cf46c/IQCNlDlLjmxiQbq7WtClgLL1AQhnV_-uSYpe1bM3HrMGJ5Q?e=7RQ658

I opened up in latest 2.6.1 profiler on Arch Linux. The capture was made on RADV. Then I get segfault:

Thread 12 "QThread" received signal SIGSEGV, Segmentation fault.

Thanks for letting us know and for providing a test case. We will take a look.
