Lots of tasks in tasklist cause crash on startup: Creating pipes for GWakeup

## What Happened

Tasks crashes on startup. The list of calendars is shown correctly, but the tasks most times are not shown. It seems Tasks crashes while loading them.

I tried to set the inode number very high, but `df -i` always shows way enough free inodes, so I don't really know if this is the problem.

## Expected Behavior

I'd expect my tasks to appear and the UI to react to my input.

## Steps to Reproduce

1. Add a Nextcloud account with really a lot of calendars and tasks (some thousands).
2. Start Tasks
3. Wait for the UI to load the tasks, but it crashes before it finishes.
