The error message corresponds to ELIBACC, an errno that I've never seen before in my life. Apparently plymouth itself sets this when it can't dlopen() a related module. According to your bug report, you have a non-standard plymouth theme configured:
/lib/plymouth/themes/bl7-logo/ubuntu-logo.plymouth
What is this theme, and what modules is it looking for?
