Crash when using "show only people list"

Description: When trying to type something into blank space afer show only people list (in gui, tracking tab, path section) petrack crashes

petrack version:

project: test_code_1clickCorrection.pet

test_code_1clickCorrection.trc

added bug label

for now, the issue can be bypassed by manually modifying the respective entry in the .pet file

another workaround, that might be a little more handy:

when inserting the range of numbers of interest

• start by typing the numbers only e.g. 86116
• then enter the minus sign 86-116

When typing the "normal" way, petrack crashes at the time of typing the "minus" 86-. Probably due to instant processing of the input data.

For solving this issues:

• make sure that wrong inputs don't lead to crashes of PeTrack
• while typing:
  • when a wrong input occurs: mark input box with a red border

created branch 241-crash-when-using-show-only-people-list to address this issue
