Description

Hallo,

Ich habe eine Testinstallation von VDR 2.4.0 mit Hilfe von yavdr ansible auf bionic aufgesetzt. Wenn ich zusätzlich vdr-plugin-xmltv2vdr installiere, crasht der VDR und im syslog gibt es eine invalid lock sequenz und eine segfault.

Die Konfiguration (xmltv2vdr Einträge aus setup.conf, die bash scripts die die xmltv Dateien erstellen, die Kontrolldateien in /var/lib/epgsources) des xmltv2vdr habe von yavdr auf trusty übernommen, wo der xmltv2vdr im Augenblick auch erfolgreich läuft.

Ich habe versucht einen Backtrace zu erstellen; jedoch weiß ich nicht, ob ich richtig vorgegangen bin:

Here is how I can reproduce the invalid lock sequences:

I am running yavdr ansible that uses the packages from this PPA:
https://launchpad.net/~yavdr/+archive/ubuntu/experimental-vdr

These packages are installed among others:
- vdr-plugin-xmltv2vdr
- vdr-plugin-epgsearch
- vdr-plugin-live
- vdr-addon-seriestimer

Configure the path to the eplists in the xmltv2vdr configuration file. (By default, xmltv2vdr looks for them at the wrong place.)

Enable the eplists in the OSD of xmltv2vdr.

Trigger a searchtimer update in live from a browser on a remote computer. Only a few seconds later, invalid lock sequences appear in the syslog, followed by a segfault of xmltv2vdr.

To make the invalid lock sequences and the segfault disappear, simply disable the eplists in the OSD of xmltv2vdr.

Today, I got an invalid lock sequence without a segfault of the xmltv2vdr plugin. However, compared to the invalid lock sequence compared above, I got this time the invalid lock sequence without enabling the eplists.
