Calibre will not launch, qml debugging is enabled

I can no longer launch calibre. I get the following output launching from console:

QML debugging is enabled. Only use this in a safe environment.
python2: siplib.c:12299: sipEnumType_alloc: Assertion `sipTypeIsEnum(currentType)' failed.
Aborted (core dumped)

Googling either of the messages has not yielded any helpful information. As far as I know, I have not enabled qml debugging in any application. I have tried installing different versions of calibre, from different repos, but all give the same message.

I really have no idea what is going on; has anyone else seen this? Any help on how to get calibre working would be very much appreciated.

zypper lr -d

please

Calibre runs fine here

It is better to install Calibre directly from their webpage, the versions from the different repos often do not work.

Repos 6, 8 and 10 are the ones I’ve tried installing Calibre from.

calibre - Download for Linux

Thanks, I’ll give that a try.

This is what I have ( TWoss is the alias for the TW oss repo )

Information for package calibre:
--------------------------------
Repository     : TWoss                        
Name           : calibre                      
Version        : 2.69.0-1.2                   
Arch           : x86_64                       
Vendor         : openSUSE                     
Installed Size : 52.9 MiB                     
Installed      : Yes                          
Status         : up-to-date                   
Summary        : EBook Management Application

Having a look at the repo list, a mix of packages from different build versions might be an issue too.

This seems to have been the cause. I did a ‘switch packages’ to the TW OSS repo, and Calibre is working again. Thanks for the advice.
