Okular crash

Today’s update of Leap 15.0 makes okular to crash regularly on clicking any pdf file. In fact, nothing happens at all.
When running okular in terminal, the following error message appears:

okular: symbol lookup error: /usr/lib64/qt5/plugins/okular/generators/okularGenerator_poppler.so: undefined symbol: ZNK7Poppler4Page13renderToImageEddiiiiNS0_8RotationEPFvRK6QImageRK8QVariantEPFbS7_ESB_S7

Using Leap 15.0, plasma 5.13.3, Frameworks 5.47.0, Qt 5.11.1, kernel 4.12.14, OS 64-bit.

Do you have additional repositories?

zypper ls -d

It also searches for and deletes Okular configuration files between hidden files

zypper ls -d

But I managed to solve the problem by updating/upgrading poppler. The “zypper up” or “zypper dup” command did not produce any result. I had to do “zypper install libpoppler …” in order to get poppler updated. Now, okular is back to work.

I do not use Plasma and sincerely I think a lot of the repositories, then all with the same priority.
But it may be that I’m wrong :\
