KeyError exception when pausing execution

Setup:

pyocd --version: 0.25.0 (latest release)
Installed in a Python 3.7.7 base
STM32L476RG based microcontroller board
Firmware uses mbed-os (RTX5 RTOS)
ST-Link V2 connected to it, latest firmware version V2J34M7 installed on it
GDB server started with pyocd gdb -t cortex_m -v
Interacted with by CLion (GDB Remote Debug target with arm-none-eabi-gdb as client and localhost:3333 as target.

At first, the GDB server is started using pyocd. Then, CLion is connected to it (using the Debug button). Then the "Pause" button is pressed. pyocd crashes immediately with an error

Hm actually this might be an invalid bug report. I've cloned the latest version from the repository and retried the same procedure, now the error is not occurring. Notice how the output beyond GDB received query: [b'Xfer', b'threads', does not contain an error anymore. Either I can't reproduce an edge case here or the error has already been fixed in master. Maybe some safeguards were added to make sure self.STATES[self._state] exists in the rtx5.py code?

If you can't reproduce it and the code good looks good in current master, I'm closing this.
