error when searching for a LF tag pm3: line 249: 2109 Segmentation fault $CLIENT "$@" #2789
Description
Describe the bug
when searching for a em4305 tag the program sometimes crashes.
The same tag works sometimes and crashes others.
To Reproduce
Steps to reproduce the behavior:
- 2.12x12mm em4305 tag placed on coil
- Run lf search
Actual behavior
terminal output this and the program crashes
error when searching for a LF tag pm3: line 249: 2109 Segmentation fault
Expected behavior
not to crash and to provide the following data
