Also with Nextcloud 25.0.2 and Onlyoffice 7.6.8 on el9:
kernel: x2t[18864]: segfault at 78 ip 00007fae92312f6b sp 00007ffe95969230 error 4 in libgraphics.so[7fae91f2e000+68e000]
occurs when listing files.
Workaround: Disable the "Use ONLYOFFICE to generate a document preview" setting.
i did - but syslog is still full of:
kernel: x2t[2335483]: segfault at 78 ip 00007fa1d5a24f6b sp 00007ffc57cf9960 error 4 in libgraphics.so[7fa1d5640000+68e000]
Workaround does not fix the issue for me
NOW ON:
Nextcloud: 25.0.5 documentserver_community: 0.1.13 onlyoffice: 7.8.0
Now: Disable the "Use ONLYOFFICE to generate a document preview" setting - fixed it for me for NC: 25.0.5
Thanks for this good advice/workaround
