Package: incron
Version: incron
Severity: normal
Dear Maintainer,
I run a server with NFS-exports. And i want to run some actions when
files and dirs are changing in these exports. For better explanation,
its the filespace for a nextcloud i want to export also as nfs, because
it's much faster on the clients than the webdav-export.
But handling files and dirs in the filesystem directly causes nextcloud
not to recognize this changes. So i want to run a files-scan only on
changed files and directories periodically for nextcloud.
When i create a new directory, incron crashes on every
IN_CREATE,IN_ISDIR event.
```

code=killed, status=11/SEGV
Dez 07 08:45:35 nas systemd[1]: incron.service: Failed with result 'signal'.
```
When i move a directory directly on the nfs-server, i works.

But when i move the dir via nfs-client, incron crashes

```
The script nc-incron-filehandle only writes the filename to a logfile.
I run this on a proxmox-server
Thank you.
