Merkuro backtrace
STEPS TO REPRODUCE
1. Launch `merkuro-calendar` from terminal.
2. The UI attempts to load views and delegates.
OBSERVED RESULT
Merkuro aborts immediately with SIGABRT / malloc corruption:
"malloc(): unaligned tcache chunk detected"
EXPECTED RESULT
Merkuro should initialize CalendarApplication and ViewTitleDelegate without
heap corruption.
