Hi,

The attached patch fixed the issue for me. Now ibus-engine-stt seems to be running correctly and I can switch to the input method without the workaround indicated in the initial report.

I noticed that there are some lint issues from the original package definition though. I didn't fixed those:

$ ./pre-inst-env guix lint ibus-speech-to-text
/home/yo/guix/gnu/packages/ibus.scm:899:5: ibus-speech-to-text@0.4.0: 

[1] 'desktop-file-utils' should probably be a native input

/home/yo/guix/gnu/packages/ibus.scm:899:5: ibus-speech-to-text@0.4.0: 

[2] 'glib:bin' should probably be a native input

/home/yo/guix/gnu/packages/ibus.scm:899:5: ibus-speech-to-text@0.4.0: 

[3] 'gobject-introspection' should probably be a native input

/home/yo/guix/gnu/packages/ibus.scm:899:5: ibus-speech-to-text@0.4.0: 

[4] label 'glib' does not match package name 'glib:bin'

/home/yo/guix/gnu/packages/ibus.scm:856:2: ibus-speech-to-text@0.4.0: 

[5] "bash-minimal" should be in 'inputs' when 'wrap-program' is used
