Segmentation fault when battery monitoring enabled #58

Closed h3ss closed 9 months ago

h3ss commented 9 months ago

Describe the bug

gBar crashes moments after startup. This occurs if the BatteryFolder configuration option is present. When this is disabled, no crash occurs.

This behavior only started after commit 6e71e8a titled "Add battery charging indication"

Steps to Reproduce

  1. Include a BatteryFolder option in the configuration file
  2. Execute gBar bar 0

Expected behavior

Battery monitoring should be able to be enabled without resulting in segmentation fault.
