grub-customizer:4508: glibmm-CRITICAL

[[e-mail]]

Hi I'm using Linux Mint 17.2 Mate when starting the program gives the script locked loading 4/11.
From the terminal gives the following error message:

(grub-customizer:4508): glibmm-CRITICAL **:
unhandled exception (type Glib::Error) in signal handler:
domain: g_convert_error
code : 1
what : Hay una secuencia de bytes no válida en la entrada de conversión

I tried to install Grub2 on a USB-3.0 stick.
(https://www.lowlevel.eu/wiki/GRUB_Installation_auf_einem_USB-Stick)

Then started Grub-Customizer, changed environment to my mount points /media/usb/sdb5 and /media/usb/sdb1.

# lsblk

└─sdb6 8:22 1 27,3G 0 part /media/usb/sdb6

=> Grub-Customizer crashed.

=> From now on Grub-Customizer crashes always immediately after I launch it.
Any idea / help ?

How did you changed environment to your mount points? You can choose partitions only when using the partition chooser.

Did you save the environment setup? This may be the reason for crashing on startup. Try to delete /etc/grub-customizer/grub.cfg (sudo rm).
