Fonts change when rockbox restart

[Segmentation_Fault]

My problem is that when i set some theme the fonts doesn't load well, I already saw the configuration theme file at .rockbox/themes and i'm sure i wrote well the font name, and yes, i'm sure i have the font in the .rockbox/fonts directory. for example when i use some theme that uses backdrop, this is loaded fine but the font does not, so i tried changing the font selecting it from fonts directory, when i do that the font changes correctly and i got the theme well, but when i restart rockbox it loads the default font.

I have an ipod video and yes i had read all the topics on this forum, thanks for your help.

Make sure the "hold" switch isn´t on when docking/charging your ipod.
If switched to hold, configuration will be cleared (you can read this on the rockbox boot screen).
