ibus: 1.5.26 does not support Spanish Latam
Current 1.5.26 package lacks the support for Latinamerican Spanish, this seems to cause issue on the keyboard layout setting English by default and not having a practical way to select that layout.
ibus v1.5.27, will reintroduce de support for Spanish Latam, so a backport might be required when that happens.
