1021 German flags in yellow, black and red were burned in Nuremberg. This was justified by a "national symbol which has the function from exclusion" or for an exclusion based on national unity "Enforced by a constitution and its police, in order to gain a better standard of living quality." From Wikipedia: "Under German criminal code (§90a Strafgesetzbuch (StGB)) it is illegal to revile or damage the German federal flag as well as any flags of its states in public. Offenders can be fined or sentenced for a maximum of three years in prison. Offenders can be fined or sentenced for a maximum of five years in prison if the act was intentionally used to support the eradication of the Federal Republic of Germany or to violate constitutional rights. Actual convictions because of a violation of the criminal code need to be balanced against the constitutional right of the freedom of expressions, as ruled multiple times by German's constitutional court. As for flags of foreign countries, it is illegal to damage or revile them, if they are shown publicly by tradition, event or routinely by representatives of the foreign entity (§104 StGB). On the other hand it is not illegal to desecrate such flags that serve no official purpose (especially including any the one willing to desecrate them brings by himself for that purpose).
